The room is clean. The location is fine since it's only a 2 minute walk from the BTS. BUT it is still far (30 -40 mins) from the common tourist attractions in Bangkok.
The internet is SO SLOW at less than 1MBPS though. Don't expect to be able to work here.
Also, they only have cable. And not smart TV.
So overall, it's good value for money. And Jenesis is a GREAT host
